Semi-localization transition driven by a single asymmetrical tunneling
P. Wang, K. L. Zhang, Z. Song
A local impurity usually only strongly affects few single-particle energy levels, thus cannot induce a quantum phase transition (QPT), or any macroscopic quantum phenomena in a man…
Non-Hermitian phase transition and eigenstate localization induced by asymmetric coupling
P. Wang, L. Jin, Z. Song
We investigate a uniformly coupled non-Hermitian system with asymmetric coupling amplitude. The asymmetric coupling equals to a symmetric coupling threaded by an imaginary gauge fi…
Exceptional point induced lasing dynamics in a non-Hermitian system
K. L. Zhang, P. Wang, Z. Song
Non-Hermitian systems exhibit many peculiar dynamic behaviors which never showed up in Hermitian systems. The existence of spectral singularity (SS) for a non-Hermitian scattering…
Simple harmonic oscillation in non-Hermitian SSH chain at exceptional point
K. L. Zhang, P. Wang, G. Zhang +1
The balance of gain and loss in an open system may maintain certain Hermitian dynamical behaviors, which can be hardly observed in a popular Hermitian system. In this paper, we sys…
